Converter inputs
The browser-based converters, bulk tool, calendars and widget calculate locally. Values typed into them are not submitted to us. Shared URLs can contain a date or code in their query string, so remove it before sharing if it is sensitive.
Analytics and logs
We use a self-hosted Umami analytics script served from stats.admk.com to understand aggregate page usage. Loading it sends normal request information such as IP address, user agent and referrer to that service. We do not use advertising trackers or sell visitor data. The web server and hosting provider may also retain short-lived security and access logs.
Local storage
The light/dark theme preference is stored in your browser’s local storage. It is not a tracking identifier.
